摘要： The driving assistance device controls lateral movement of the vehicle. The driving assistance device includes a steering operation actuator that steers the wheels, a detection device that detects the position of the driver's hand touching the steering wheel, and an electronic control unit that controls the lateral direction of the vehicle. In lateral control, the electronic control unit controls the steering operation actuator so that the vehicle laterally moves to the right when a hand touches the right portion of the steering wheel, and when the hand touches the left portion of the steering wheel. In this case, the steering operation actuator is controlled so that the vehicle laterally moves to the left.

摘要： A vehicle is capable of compensating for steering control based on vehicle's intrinsic factors and environmental influence factors, thereby performing steering compensation control accurately. The vehicle includes: a storage unit; a driving unit to drive a steering device; a sensor to acquire detection signals including a steering angle and a steering torque; and a controller to determine whether the vehicle is in a predetermined stable running state based on the detection signals, wherein, when the vehicle is in the predetermined stable running state, the controller extracts reference information including a relationship between the steering angle and the steering torque at one or more past time points, stores the reference information in the storage unit, and controls the driving unit based on a difference between the reference information and the steering angle and the steering torque.

摘要： A driving support ECU initializes a target trajectory calculation parameter at a start of LCA; calculates, based on the target trajectory calculation parameter, a target trajectory function representing a target lateral position which is a target position of an own vehicle in a lane width direction in accordance with an elapsed time from the start of LCA; calculates a target control amount based on the target trajectory function; when a steering operation by a driver has been detected, again initializes the target trajectory calculation parameter; and recalculates the target trajectory function based on the target trajectory calculation parameter.

摘要： Various embodiments of an apparatus for changing the in-air pitch and/or roll of a land craft are described herein. The apparatus may include a steering input mechanism, a support structure, and an articulator. The apparatus may include one or more of a pitch-forward input mechanism, a pitch-back input mechanism, a roll-right input mechanism, and a roll-left input mechanism. The vehicle may include a set of wheels on which the vehicle travels over ground. The steering input mechanism may receive steering inputs from a driver of the vehicle. The steering input mechanism may receive pitch and roll control inputs from the driver. The support structure may connect the steering input mechanism to the vehicle, at least one of the wheels, or the vehicle and the at least one of the wheels. The articulator may rotatably connect the steering input mechanism to the support structure.

摘要： A controller for a power steering system estimates rack force and its derivative, such as based on lateral acceleration, yaw rate, vehicle speed, or other parameters. A control torque is calculated based on the rack force, its derivative, and the vehicle speed and is summed with an input torque from the driver to determine an amount of assist torque to provide. The control torque may be a shape function that has a sign determined by the sign of the derivative and a magnitude that decreases from a maximal value with increase in the magnitude of the rack force. The maximal value may be determined according to vehicle speed.

摘要： A system may comprise a plurality of sensors configured to transmit sensor information regarding a speed of a machine, a position of an implement of the machine, a payload of the machine, a grade of a surface on which the machine is traveling. The system may further comprise an electronic control module configured to receive steering command information regarding a steering command of the machine; determine, based on the steering command information, one or more articulation parameters associated with the steering command, determine the speed, the position of the implement, the payload, and the grade based on the sensor information. The electronic control module may be configured to determine one or more articulation parameters thresholds based on the speed, the position of the implement, and the payload of the machine; and modify the steering command when the one or more articulation parameters exceeds the one or more articulation parameters thresholds.

摘要： Embodiments of the present invention provide a control system for a motor vehicle comprising: means for detecting a side-slope condition in which a vehicle is traversing a side-slope; and means for controlling an amount of torque applied to one or more wheels to induce a turning moment on a vehicle, the system being configured to cause a turning moment to be induced in a direction opposing side-slip of a trailing axle in a down-slope direction relative to a leading axle.

A minimum velocity allowing the desired steering angle to be reached is determined. The velocity of the vehicle is increased to the determined minimum velocity. The rack is moved to the rack position needed.

摘要： A method of tuning a calibration table for an electric power steering system includes connecting the electric power steering system to an actuator machine, and communicating a control input from a vehicle simulator to the actuator machine. Input forces and steering angles are applied to the electric power steering system with the actuator machine, based on the control input. The electric power steering system is controlled with a steering controller, to apply a steering setting, i.e., and assistive torque. The steering controller uses the calibration table to define the steering setting, based on the applied input forces and steering angles. A steering torque in the electric power steering system generated in response to the applied steering setting is sensed, and communicated to the vehicle controller, thereby establishing a closed loop, feedback system. The calibration table may then be re-defined based on the sensed steering response for the applied input forces.
